All beings since their first aspiration till the attainment of Buddhahood are sheltered under the guardianship of Buddhas and Bodhisattvas who, responding to the requirements of the occasion, transform themselves and assume the actual forms of personality.

Thus for the sake of all beings Buddhas and Bodhisattvas become sometimes their parents, sometimes their wives and children, sometimes their kinsmen, sometimes their servants, sometimes their friends, sometimes their enemies, sometimes reveal themselves as devas or in some other forms.

"All memories and thoughts are the union of emptiness and knowing, the Mind.Without attachment, self-liberating, like a snake in a knot.Through the qualities of meditating in that way,Mental obscurations are purified and the dharmakaya is attained."
